Compact Vane Anemometer
testo 416
The compact testo 416
anemometer with permanently
attached vane probe with
telescopic handle (max. 890mm).
Volume flow is shown directly in
the display. Accurate volume flow
calculation due to easy input of
duct area.
Timed and multi-point mean
calculation provide information on
mean volume flow.
Min/max values can also be
shown in the display. The Hold
function enables you to freeze the
current reading in the display.
• Direct display of volume flow
• Multi-point or timed mean
calculation
• Max/min values
• Hold button to freeze readings
• Display light
• Auto-Off function
